Let your eyes look directly forward, and your gaze be straight before you.
Ponder the path of your feet; then all your ways will be sure.
Do not swerve to the right or to the left; turn your foot away from evil. - Proverbs 4:24-27 (ESV)
My son, be attentive to my wisdom; incline your ear to my understanding, that you may keep discretion, and your lips may guard knowledge. - Proverbs 5:1 (ESV)
